<h1>General dynamics properties</h1>

<p>The general dynamics properties  dialog is ocated at [Menu bar --&gt; Tools --&gt; Dynamics properties]. You can also open the dialog with a click on its <a href="userInterface.htm#toolbars">toolbar</a> button:<br>

<li><strong>Dynamics enabled</strong>: allows enabling/disabling dynamics calculations for the entire <a href="scenes.htm">scene</a>.<br>
</li>

<li><strong>Engine to use</strong>: the dynamics engine to use. Bullet stands for the <a href="dynamicsModule.htm#bullet">Bullet physics library</a>, ODE for the <a href="dynamicsModule.htm#ode">Open Dynamics Engine</a>, Vortex for the <a href="dynamicsModule.htm#vortex">Vortex Studio engine</a> and Newton for the <a href="dynamicsModule.htm#newton">Newton Dynamics engine</a>. Each engine has specific strengths and weaknesses. A <a href="simulation.htm">simulation</a> running fine with one engine doesn't always mean that it will also run fine with the other engines. Each engine has specific parameters that can be set globally (see <strong>Adjust engine parameters</strong> hereafter) or locally (in the <a href="shapeDynamicEngineProperties.htm">material properties</a> or in the <a href="jointDynamicEngineProperties.htm">dynamics engines properties dialog related to joints</a>). Make sure you read the respective engine documentations to achieve best parameter settings.<br>
</li>

<li><strong>Display contact points</strong>: allows displaying contact points between respondable <a href="shapes.htm">shapes</a>.<br>
</li>

<li><strong>Adjust engine parameters</strong>: opens the <a href="dynamicsEngineDialog.htm">dynamics engines general properties</a> dialog, which allows adjusting engine-specific global parameters.<br>
</li>

<li><strong>Gravity</strong>: the amplitude and direction of a constant force applied to all non-static shapes (e.g. gravity).<br>
